When the Krakau came to Earth, they planned to invite humanity into a growing alliance of sentient species.

This would have worked out better for all involved if they hadn’t arrived after a mutated plague wiped out half the planet, turned the rest into shambling, near-unstoppable animals, and basically destroyed human civilization. You know—your standard apocalypse.

The Krakau’s first impulse was to turn their ships around and go home. After all, it’s hard to establish diplomatic relations with mindless savages who eat your diplomats.

Their second impulse was to try to fix us.

A century later, human beings might not be what they once were, but hey, at least they stopped trying to eat everyone. Mostly.

Marion “Mops” Adamopoulos is surprisingly bright (for a human). As a Lieutenant on the Earth Mercenary Corps Ship Pufferfish, she’s in charge of the Shipboard Hygiene and Sanitation team. When a bioweapon attack by an alien race wipes out the Krakau command crew and reverts the rest of the humans to their feral state, only Mops and her team are left with their minds intact.

Escaping the attacking aliens—not to mention her shambling crewmates—is only the beginning. Sure, Mops and her assortment of space janitors and plumbers can clean the ship, but flying the damn thing is another matter. As they struggle to keep the Pufferfish functioning and find a cure for their crew, they stumble onto a conspiracy that could threaten the entire alliance.

A conspiracy born from the truth of what happened on Earth all those years ago…

The Krakau came to Earth in the year 2104. By 2105, humanity had been reduced to shambling, feral monsters. In the Krakau’s defense, it was an accident, and a century later, they did come back and try to fix us. Sort of.

It’s been four months since Marion “Mops” Adamopoulos learned the truth of that accident. Four months since she and her team of janitors hygiene and sanitation specialists stole the EMCS Pufferfish and stopped a bioterrorism attack against the Krakau homeworld. Four months since she set out to find proof of what really happened on Earth all those years ago.

Between trying to protect their secrets and fighting the xenocidal Prodryans, who’ve been escalating their war against everyone who isn’t Prodryan, the Krakau have their tentacles full.

Mops’ mission changes when she learns of a secret Krakau laboratory on Earth. A small group under command of Fleet Admiral Belle-Bonne Sage is working to create a new weapon, one that could bring victory over the Prodryans … or drown the galaxy in chaos.

To discover the truth, Mops and her rogue cleaning crew will have to do the one thing she fears most: return to Earth, a world overrun by feral apes, wild dogs, savage humans, and worse. (After all, the planet hasn’t been cleaned in a century and a half!) What Mops finds in the filthy ruins could change everything, assuming she survives long enough to share it.
